Creep Over about 900°F (482°C), deformation under stress is plastic rather than elastic, so the yield point as determined by the short-time tensile test is higher than the creep or Fastener Ultimate Tensile Strength vs. Yield Strength yield point and temparature relationship of high tensile steelFigure 1 shows the relationship of yield strength to ultimate tensile strength. Another way to envision this relationship is if a load is applied to any point less than the yield strength and then removed, the fastener will return to its original dimensions (elastic deformation).Factors that Affect the Yield Strength of Metals | Metallurgy(i) At high temperatures, the metals become soft, its yield strength decreases (Fig. 1.13) and hence low forces are required for forming. This reduces the cost of equipment needed for the process. (ii) Metals are more ductile at higher temperatures and their formability in hot state is higher than in cold state.
Increase of the temperature means input of the heat energy, which cause agitation of molecule and cause the stretching of bond chain. So the net bonding energy will be changed with the Heat energy input and will be lowered proportionately.
